HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2121, 4795 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 2121, 4795 is 7 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 2121, 4795 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 2121, 4795 is 7.
HCF(2121, 4795) = 7
HCF of 2121, 4795 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2121, 4795 is 7.
Highest Common Factor of 2121,4795 is 7
Step 1: Since 4795 > 2121, we apply the division lemma to 4795 and 2121, to get
4795 = 2121 x 2 + 553
Step 2: Since the reminder 2121 ≠ 0, we apply division lemma to 553 and 2121, to get
2121 = 553 x 3 + 462
Step 3: We consider the new divisor 553 and the new remainder 462, and apply the division lemma to get
553 = 462 x 1 + 91
We consider the new divisor 462 and the new remainder 91,and apply the division lemma to get
462 = 91 x 5 + 7
We consider the new divisor 91 and the new remainder 7,and apply the division lemma to get
91 = 7 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 2121 and 4795 is 7
Notice that 7 = HCF(91,7) = HCF(462,91) = HCF(553,462) = HCF(2121,553) = HCF(4795,2121) .
